I recently obtained an E46 compact from 1998. Because I wasn't going to do anything with it for at least a few weeks, I figured it was a good idea to disconnect the battery.

Admittedly I should have smelled trouble when I couldn't lock the doors without the battery hooked up, but being preoccupied (i.e. stupid) at the time, I connected the battery, locked the car, disconnected the battery, and closed the hood. :facepalm:

So now I'm faced with a challenge to open it up without the use of excessive violence.
The locks do not respond to turning the key (no more mechanics?) and I can't figure out how to open the hood.

I didn't spend a lot of time on this yet, was just faced with the problem as I quickly wanted to check the mileage on this thing and it is parked about 100 miles down the road.

So I figured next time I'd come prepared, but I didn't find anything on this problem the Google way.
Am I really the first and only idiot, or am I simply missing the obvious?

Yeah, the lock SHOULD open for you. That's why BMW put a keyhole there, so if people's batteries die, they will still be able to open the car. Even the E9x's have a key blade inside of the key fob.

I guess the ability to read a manual these days is too much to ask.

From the manual.
Manual Operation (in the event of electronic malfunction)
Turn the key to the extreme left or right to unlock/lock the door.

:facepalm:

Well, I assume I have the right key. The electronics worked when I locked it. But turning the key has no effect what so ever.
As mentioned, I couldn't lock the car either with the key and the disconnected battery.

I'll be back there later this week and give it another shot. Try the passenger side and the trunk. Will keep you updated.
Thanks dor the replies anyway. Feel slightly better knowing that this is not a "normal" issue.

See he's in Holland, so his manuals in Dutch, so may be he don't how to read Dutch, because he's American or other nationality.
How about this theory?

This theory sux :facepalm:. BMW locks do need power. I remember my doors would not lock, nor fully close, when I disconnected the battery.

If you're hood is open you can apply power the under hood jump terminals with a jump box or charger, or even another battery. Did you turn the key twice (in the door)? In the trunk, is you have the correct key, it should open with the key. The key lock in the trunk is mechanical and unless you have the wrong key or the lock is broken it will open. When I'm replacing a quarter panel on these cars I ALWAYS have the battery out (can't weld on a car with the battery connected). And as I weld, I need to check my fit very often, I open and close the trunk repeatedly with the key.

If this won't work,

Turn the key all the way in the unlock postion while holding it there pull on the handle. If it doesn not work don't worry, some of the cars that feature breaks. the way i get into those cars is to go under to the starter apply power to the main starter cable. and then ground the other lead. this will power the electrical system up and allow you into the car.

Well, it seems I caused quite a comotion here.

I went to pick up the car today and had no luck turning the key. The trunk opened fine however and provided easy access to the back from where I could open the doors with the handle.

After I reconnected the battery, I tried the lock again but still it didn't budge. I guess I simply have a broken lock.

Problem solved.
On the way home, my right side window fell out of its slots. I noticed one light unit is held in place with clear tape, and as I'm typing this message the alarm keeps going on and off for no apparent reason.

So I might be back soon for more tips, tricks and insults.
